Just got through replacing the head gaskets in my '93 6.5, well kinda, I still gotta few things left to bolt back up. Let me tell you it was not much fun to do in an apartment parking lot in South Texas in 95 degree weather, but it wasn't nearly as bad I thought it would be. The engine has 360,000 miles on it so I thought I would have problems with some of the bolt but they all came loose fairly easily. This is the first major repare that's ever had to be done to it so I can't complain. I also turned up the pump slightly while the drivers side head was off since it was easy to get to. I do, however, have a question about bleeding the fuel system before the first start up. Should I bleed from the injector side of the line? I don't see how I could get to the lines at the pump, but I also don't think I can get to the injector lines at the injector after I get the turbo back on. Thanks in advance for any advise.

I'll be bleeding from the injector side. It is possible to get to the injectors while the turbo is on. I was able to remove pretty much everything but the head with the turbo on. It was actually the last thing I removed before I removed the head bolts.

I always leave the turbo off until after I've had it cranked. I just plug the turbo oil feed line.

I hot wire the lift pump to run, bleed the filter, let the lift pump run a couple minutes, then crank the engine over with the injector lines backed off about half turn from finger tight. Crank a few seconds and check, usually get fuel to the injectors after the second or third try. Snug the wet injectors, if it cranks snug the remaining injectors, I always go over all the injectors again to make sure the air is out and each cylinder is firing.

Some guys just tighten everthing up, but I dont know how much cranking it would take to work the air out. When I did my 93 it sat for five months torn apart and it fired up pretty quickly with just the three year old batteries that had been sitting, no charger.

Oh yea, just bleed the lines at the injector.

HTH

Where in texas are you? I'm in the north east part by Texarkana.

I just replaced head gaskets in a 94 6.5 F code.. We replaced the fuel filter at the same time, and she fired up after 2 tries of about 3-5 seconds each to bleed air out. The other thing you can do is open up the water in fuel valve by the thermostat housing. If it drips fuel out when you open that up, you're pretty close to having all the air out and she should start up fairly quickly.

Thanks for the advise guys. I should be ready to start it up by Saturday. I replaced the filter housing today after work and got a few more things bolted up. After I get it started should I crack the lines at the injectors to make sure there isn't any more air in the system? Oh yeah, midniteplowboyy I live in San Antonio.

You dont have to bleed them again, but I do.

The first time I tighten the line, I just barely snug it, once I have them all snug I go over each one at a time to let the rest of the air out and make sure that cylinder is firing.

I love it down in San Antonio. I was stationed in Fort Sam for my AIT back in the day.

Got everything back together. Just need to bleed the system, so it should be running by Saturday.
